We Check Out AMS Performance's Turbo Test Rig

By Khiem Dinh

A couple years ago, AMS Performance became a Garrett turbo distributor. In order to best serve their customers, they needed a way to test all the turbos to determine how they performed. A turbocharger gas stand is extremely expensive. An engine dyno cell is very expensive. An old Evo shop car? That could be made to work as the turbo test rig.

How to Pass Tech Inspection for The Drift League and Other Events!

By Mike Kojima

As the Technical Director for The Drift League, I was pleased that the quality of many of the Pro-Am cars that myself and Nikita Rushmanove were high and we have plenty of solid cars in the series. On the other hand, I was dismayed at the fact that NONE of the cars we inspected passed tech the first time through!

Bringing the Heat: Under Control!

by Frank Ewald

With our first track day and Knox Mountain Hill Climb 2018 now behind us, we can say without question that the HeatShield Products and the Koyorad have absolutely increased the cooling capacity of the NX GTi-R on the track. Our benchmark temperatures were set last October on a cool and sunny day. The daytime high was 16°Celcius. The temperatures we checked on May 5 and it was a sunny day and the ambient temperature was 22°Celcius (that's about 72°Fahrenheit). The temperatures were checked after the car had been out for the second session and, as this was a CACC Time Attack event here at Mission's River's Edge Road Course, you can appreciate that the car was being pushed. Two weeks later the NX was at the 61st Annual Knox Mountain Hill Climb; the runs up the hill showed an amazing difference one year later. The extensive improvements to the cooling system absolutely worked.

Project DC2 Integra, Testing the Fluidampr Crank Pulley

By Mike Kojima

We have big plans for Project Integra B18C engine.  Instead of swapping to a K Series engine to make easy big power, we are going to build up the older but still noteworthy B Series engine that the car comes with. Something that is relatively easy due to this engines huge level of aftermarket support.

A Proper Primer on Personal Protection

by Erik Jacobs

In the time between the SC300 getting dyno tuned and our first track day (complete with transmission soup), I had some extra shopping to do. It turned out that all of my personal safety equipment had timed out, and it all needed to be replaced with current gear. This is not an inexpensive proposition. For the average track day, a brain bucket is all that’s needed. But we had built a full-on race car and were intending to go wheel-to-wheel -- more would be required. And, generally speaking, it doesn’t hurt to have all the safety gear you can afford / bear to purchase.

Project SC300 Road Racer: Part 17 - Get out there! Or not...

by Erik Jacobs

With the car idling and most of the core sensors configured, we needed to keep moving forward in our electronics configuration in order to get to a point where we could actually drive the car. Technically we could drive the car right now, but without a functional dashboard that wouldn't be a very good idea - it's kind of hard to drive with a laptop in your... lap.

Controlling the Heat: KoyoRad

by Frank Ewald

In the last article we discussed how HeatShield Products were being used to contain the heat. This article is looking at the installation of a Koyorad aluminum radiator. It is this author's perspective that the Koyorad radiator has long been viewed as one of the best rads available for the Nissan SR20. The installation in the NX GTi-R was quick and painless. Koyorad is a very well known radiator company that build incredible aluminum racing rads. This new rad is a key part of optimizing the cooling system.

Project GT3RS Getting More Power With Dundon Motorsports Part 2

By Mike Kojima

The Porsche GT3 RS is a supercar with state of the art engineering in the powertrain department.  It has a naturally aspirated 6 cylinder flat 6 that pumps out an amazing 125 hp per liter.  The 9A1 engine has an 8800 rpm redline and a stratospheric 13:1 compression ratio which it somehow runs with on pump gas, even California's crappy 91 octane pee water, with the aid of direct injection.

Project SC300 Road Racer: Part 16 - We have ignition!

by Erik Jacobs

In the last segment, we said that we had finished wiring everything, but that’s not quite true. There were just a couple of finishing touches to sort through and then we would be able to power up the chassis and start programming devices!

Inside the 1000 hp LS, Dai Yoshihara's Formula Drift Powerplant

By Mike Kojima

MotoIQ Garage has taken over the development of Dai Yoshihara's engine program for the last two years from a famous high dollar engine builder. The previous engine had decent power but the reliability was lacking. We were experiencing some sort of engine related issue every few events and halfway through the season, the engine performance would degrade and a fresh engine would need to be installed.

Controlling the Heat: HeatShield Products

by Frank Ewald

In the last article on the NX GTi-R there should have been no doubt in anyone's mind that the temperatures in the engine bay and the engine itself were bordering on the extreme. Temperatures that were under control in 30 minute track day sessions were now spiraling upwards. The larger turbo, the tighter clearances when the engine was built with forged parts, and the loss of the mystical factory manifold heat shield when I transported the NX across the country have all conspired against me.

Can an Oil Change Make More Power? We Test Idemitsu ZEPRO Eco Medalist and Find Out!

By Mike Kojima

Can you make significant power gains just by changing oil?  In the past, we have proven that switching from a lower grade mineral oil to a premium synthetic oil can be good for a couple or three hp. However, is it possible to make serious gains in power from just an oil change by changing the viscosity of the oil as well as the type?

Ryan Passey's Amazing Mazda Hyper Miata

By Mike Kojima

We have always liked the super-efficient cars of Moti Almagor's Blackbird Fabworx. His cars have a distinct signature; lightweight, elegant, very fast with very little horsepower. Focus is put on maximizing handling, braking and cornering grip in a simple package. Recently at the last Global TIme Attack event at Buttonwillow raceway we got to check out Ryan Passey's, of Goodwin Racing, 1990 Mazda Hyper Miata that was built by Ryan in collaboration with Blackbird Fabworx.

How to Build a 5.0 Coyote Engine on Any Budget

by Mark Gearhart

Many people look at the 2011-current Coyote 5.0 engine platforms as a complex and expensive engine to build. In reality, they are actually very cost effective and can be tailored from mild to wild with ease. Want to make 350 horsepower or 1,500+? No problem. In this article we are going to explain the different levels of Coyote engine building. We teamed up with a host of manufacturers and L&R Engines to build us a Coyote engine for road racing duty on Project BOSS 302Revival.

WATCH:  IMPROVING the R35 GT-R! Part4 - Brembo Brake Rotors and Pads

MotoIQ Video

Join us on our multi-part journey to improving what is arguably the best car ever made. Inexperienced "tuners" can easily ruin the R35 GT-R's performance prowess by just throwing parts at it without giving any thought to how all the parts are going to work together. That is NOT how we do things here at MotoIQ!

In Part 4 of our series we install Brembo rotors and pads!

Nerd Alert Part 2! SKYACTIV-X: Were Our Predictions Correct?

by Karla Pestotnik

When Mazda first announced its infamous, new SKYACTIV-X engine, we made some preliminary guesses about its workings before any information was released. Guesses are guesses, but now that Mazda has released more official information about the all-new and exciting Homogeneous Charge Compression Ignition (HCCI) engine, it seems that we weren’t too far off. We recently got to poke around and even test drive their ten million dollar prototypes!

WATCH! In-Depth Look: Fredric Aasbo's 2018 Formula Drift Toyota Corolla Hatchback

MotoIQ Video

Last fall, we took a long look at Fredric Aasbo's Formula DRIFT Toyota Corolla iM, but he's back for the 2018 season with a brand new late model Corolla hatchback. With a new car we had to make another trip to Papadakis Racing to take a deep look inside. Once again, Mike Kojima walks around the new Corolla Hatchback with builder and team owner Stephan Papadakis. We also take a peek at Steph's shop and some of the genius stuff going on inside one of the smallest, lightest, and most powerful pound per pound powerplants in all of Formula DRIFT, the Toyota 2AR.  Come with us and see the details up close of one of the most well thought-out Formula DRIFT machines.
